Zdoll whom it mog oonc'eiwi Be'itknown that l, lamai J. Benz-man, a citizen of thellnited States, residing at wampsoott, State of lilassachusetts; have invented certain Improvements in Presses, of whieh the following description n ronnection with the accompanying drawi gs i s a specification, like 1 iit'erenee rharaotersvonthe drawings indioating like parlisin the several figures.

' y This invention relates to presses in which the 'presser lnen'ibers are not only relatively movable in the pressing direction but in which they are alsorelati-vely movable in another direction or in other tl-ireetions,- and especially to presses in' which the presser menibers are relatively movable into different pressing relations to work preferably carried by one ofsaid members. ,More par ticularly the invention relates to presses in which a presser member is movable: into di f- V fer-lent :pii'essiire-applying relations to-Va bed 7 -upon which the-work s supported,

in its illustrated preferred embodiment the inventionis shown as applied to press in-which the bed; is adapted-to the supportot qworl; inthe filllll fif sheet material "fromvhichbla'nksmaybe cut bythe use of freely movable dies. the n'ovision of improved means for sup porting the presser member for movement in aplane parallel to the worksuppoi V1119 (3 bed and. also for movement toward and from the bed in pressure applyingr operations the oonstrurtion and arrangement being preterably such that thepresser member projects over the work supporting bed from a sunport-at one side-of: the bed into the path of movement of the operating means for the pressermernber.

Another important object oi, the invention is to provide, in anorg anization designed to utilizetlreelv movable dies cutting operations upon sheet material, a'presser,men'iher vwhich is mounted for movement along its supportat the rearof the work supporting bed and independently of its operating mechanism'so that the latter mechanism bearsno part of the weight of the presser vrr in the county of Essex and v An important object ofthe invention is ember, a feature oi markecliinportanoe no the-advantages of economy of power and increased durability of the niachineorganization. v w 7 I In a practieal embodiment ofthe invention, the movable presser member is mounted one stationam support at the rear of the work supporting bed. the construction and arrangement being preferably such that the pressermember is movable along the stationary support by power means under the control of the operator to attain co-operative relations suoressively with all portions of the work sup portingbed. i

It is a further object of the invention to provide a presser member with power means for moving it along its support to any (lesired position over the work supporting; bed and with power means for causing pressureapplying movements of the presser member wherein a manually operable controlling means for both said power means is mounted on and movable with the presser member.

Other features of importance reside in an organization in which the movable presser member projects from its support on the frame oi the machine into a. space between the worl: supporting bed and the operating means For the presser member, the space referred to being; of such dimensions that there is room for all neressary and desirable manipulation of the work and of the freely movable dies and for the access of light to the work,

Other objects and. advantages of the invention will be apparent from the Following: detailed description and will be pointed out in the claims In the drawings-'- Fig.1 is a front view of one embodiment of the invention;

Fig. 2 is an end elevation of the machine shown in Fig. 1;

i Fig. is a detail perspective view partly in sertion showing: the movable presser member and the means for moving the same relativelvto the work supporting bed;

Fin. 4: is a section through the movable presser member showing the manner of mountin; the same in its carriage, and

Fig 5 is a detail view showing the clutch for connecting the presser member to the means for shitting-the presser member rela tively to the work supporting bed.

i In the I illustrative machine the lower presser member or work supporting bed 8 is supported adjustably upon the frame mem- "bers 10 i'n-the manner'that is well-known in machines of this type, adjusting screw threaded members '12 being provided. in co- -oper ation with the extensions 14; from the '.bed support 15 to'adjust the work support ing bed in a vertical direction. Mounted in the frame of the machine is a main shaft 16' carrying at one end the power pulley 18,

connections being provided between the shaft and a cross head 20 to reciprocate the 'latter toward and from the work supporting bed 8, the connections comprising a pair of bars 22 at each end of the cross head fixedly attached thereto and connected in pairs at their lower ends by yoke members 2a to which there are pivoted pitinen 26 one adacent to each end of the shaft, the said pitinen carrying the usual strap portionsarrangedin engagement in the usual manner,

I being of the well-known one revolution type like that shown. for instance, in the patent to Arthur Bates No. 921,503, granted May '11,

The other presser member which is urranged tococperate with the work supporting bed 8 is mounted independently of the cross head 20 and is arranged to project into the space between the cross head and the work supporting bed, the relationship of these parts being such, as clearly disclosed in Fig. l of the drawings, that room is pro -v1ded for free n'ianipulation of the work and of the dies in locating the latter relatively to the work and for access of sufiicient light to enable the operator to position the dies as'desircd and in accordance witlrthe characteristics of the material being operated upon. ln'the illustrated embodiment of the invention the prcsser member 30 is mounted upon a stationary support 33 extending longitudinally of one side of the work supporting bed and preferably ina plane above the bed, bracketsfi l: being arranged to hold the support 32 fixedly in position, the said brackets being attached to or made integral with the frame members 10 as clearly disclosed in Figs. 1 and 2 of the drawings.

'Means are provided for mounting" the presser member 30 for movement along its support 32 so that thepresser member may :be located in any desired relation with re- 7 spect' to various portions of the cutting bed 8, the said means comprising preferably an 7 7 arm SGp'rovided with means for slidably engaging surfaeesofi the supporting meni ber 32. In order to reduce, as far as possible', any friction" between the arm and its support there are provided rollers '88 (see Fig. 5) carried by an-extension iOr of the 1 arm, the said extension being. arrangedtoj engage overthe upper edge of the-support 32 and position the rollers 38 inengagement bar 32 while still other rollers i l on the arni that the presser member may be operated toward and from the work supporting bed to apply pressure upon dies'located upon the work. The means for supporting the presser member 30 comprises, in the illustratedembodiment of the 'invention,"a carriage "l8 movable along the arm 36"in'directions toward and from the supporting bar 32, the

'with the rear surface .ofthesupport-or sup- 7 porting bar 32. Other rollers 42011 the arm 36 engage the upper edge of the supporting engage the lower front surface of the sup-f porting bar, the arrangement of the: rollers mounting for the carriage consistingof rolls 7 I or wheels 50 guided along passagew tracks 52 in the forked or bifurcated portions of the arm 36. The heels or rolls 50 are mounted at the ends of shaft 54 carried by the carriage 38 and are of such dimen sions relatively to the tracks or passage-1 ways52 as'to be received rotatablyftherein for'movement longitudinally of the passageways or tracks 52 but without movement in a vertical direction in thetracks. words, the rollsor'whee1s5 0 fit snuglyin the passageways or tracks52 so that-there is no movement vertically of the carriage 48 with respect to the arm 3(5during the pres sure-applying, movements of the presser member 80. The sa-id presser member is mounted for movementtoward and from the work supporting bed through a sliding con nection with the carriage 48, the illustrative construction comprising tubular bearing portion. 54 in the carriage 48 designed to receive slidably the shaft or post 56to the lower end of which the pressermernber 30" is" connected by being. pressed upon or pinned to the reduced portion 58 of'the post. 7

Referring to the disclosure'in Fig. 4, it will.

In other be observed that the 'presser member 30 has 1 a shoulder portion GOwhich is held'normally in abutting relation to a plane su rfaceon the .under side fof'the carriage 48 by yielding means comprisingpreferably springs! 62 attachedQat-their lower ends di- 7 rectly to the member 30 and at'theirnpper ends to pins or studs or other projections 64- located adjacentto the upper end of the "shoulder 60 moved into contact with the plane surface constructions. ll hilethe post 56 carriage.

securing rods 68 and spacing members '10-, i perform the stance asithat shown at 66 in the post-56. his a detail of the construction of the arm 36 there are provided rods 68 carrying-spacing members 70 and extending through the outer ends of the forked or bifurcated portions of the arm 36 so as to maintain the said portions against lateral movement relatively to each other duringthe strains inciadditional function of limiting the movement of the carriage outwardly or toward the front of the machine as the carriage travels along the tracks "or guide ays 52. From an inspection of Figs. 1. and

V 2 of the drawings it will be' observed that the post 56 extends upwardly beyond the carriage 5% almost into 'contactwit-h the lower surface of the cross-head 20. It will be clear then that upon reciprocation of the cross head the presser member will partakeof the downward movement of tee 'cross-hea-d through contact of the crosshead with the upper end of the post-56 and that a pressure applying operation of the presscr member 30will take place with rcspect to work upon the work supporting bed 8. If, for instance, blanks from sheet material either'ot one layer or of a multiplicity'of layers, the said material is placed upon the supportin; bed 8 and a die 72 located thereon in the dcsired position. 7 The presser member 30 is positioned over the die so that upon down ward movement of the presscr member 30 the die will be forced through the work to cut blanks therefrom. As heretofore stated the prcsscr member and its supporting arm 86 are movable along the supportinp bar 32so as to brino'the presser member over any selected portion of the work supporting" bed. The arrangement just described issuch that the prcsscr member may he moved away from over the die after a dieinn-out operation to permit 01"? the removal of the die and its relocation with respect -to.the work. Then the presse'r member may again be moved over the die and theo ngra tion repeated' asabove described by wh;

. jacent to each end the supporting bar it is desired to cut tioninp' oi the presser members relatively to each other there is provided power means tor moving; the movable presser member, the construction and arrangement being; prefer ably such that the operator can connect the presser member to the power means throng-1h the manipulation of the same handle i l through connections hereinafter described.

The power means lior moving the presser member to various positions over the work supporting bed is shown in the illustrative machine as comprising an endless cable 76 passing around pulleys 1 8 and 80 mounted upon stub shafts carried by brackets 82 ad 32, the brackets in the constructionshown being mounted upon the ends of said supporting bar. The pulley 30 is constantly driven by connections from the main shaft 16 of the machine. the said connections comprising in th illustrative embodiment oi? the invention a pulley member 84 (Fig. 1) attached to or integral with the power pulley 18, a cable or pulley belt 86 passing around the pulley 8% and extending to and around a second pulley 8S fixedly scoured to a shall: 90 carried by a bracket 92 extending from the frame of the machine. Drivingconnections are provided between the shalt 90 and the cubic pulley 80 which comprise inthe illustrated construction a worm gear 94: scoured on the shaft 90 arranged in constant mesh with a gear 96 on a stub shaft 98 which carries fixedly attached thereto a pulley 100. Passing around pulley 100 a cable or belt 102 by which power is transmitted to another pulley 10d integral with or attached to the pulley 80. If the connections just described be traced it will be lound'that the cable T6 is driven constantly in one direction by power derived from the constantly rotating power pulley 18 onthe main shaft of the machine. It the prcsser member which is movable along its supporting bar with which the cable 76 is arranged in parallelism be connected to the upper run or strand 106 of the cable 76 the presser member will be carried to the right in Figs. 1 and 3 and it the prcsser memher be connected to the lower run or strand 108 of the cable 76 the presser member will be carried to the left as viewed in the same il 'llllQS. Means therefore proi ided for connecting tho :u'osscr member to-thc con stantly running cable in such manner that the time and duration of the connection between the presser member and cable can be determined bythe operator, the construction provided being, moreover, or" such nature as V to require the very minimum of effort on the 7 either direction as desired. In the illustra- '10 party of the operatorin effecting the connections for moving the presser member in tive embodiment of the invention the runs or I strands oit the cable are arran ed to ass transversely across the supporting, arm 36 closely adjacent to portions 116, 112 of the arm, the construction being such that the portions 110, 112 serve as clamping members rigidly attached to or integral with the arm.

.The co-operating clamping member is provided in the construction shown with two clamps or clamping members 11% mounted preferably on a vertically arranged shaft 117 to extend, in opposite directions theretrom'so that upon oscillation of the shaft one clampmg *member 11 1, earned thereby will be caused to cooperate with the stationary clamping member 110 on the arm while upon oscillation of the shaft in the other direction' the other clamping member 111 will be I caused to clamp the other run of the cable against thestationary clamping member 112 opposite the same, the arrangement being such that the presser member may be caused to move in the desired direction by selectively 'operatingthe clutches or clamping members to grip either the upper or lower run or strand of the constantly moving cable 76.

Normally the clamping members 114 are so disposed with respect totheir co-operating clamping members 110 and 112 that the runs -01"; strands of the cable pass freely between the clamping members and thus the presser -member 30 remains stationaryv until the proper clutch or clamping member is oper ated by the operator. The means for enabling the operator to operate the clutchor project-ion 120 on the handle 74, the other 'end of the link or rod 116 being also pivotally attached to an arm 122 extending laterally from the shaft 117. Upon inspection of r Fig. 3 of the drawings, it will be seen that member 30.

65,.of'the handle 74 tothe right as viewed in upon turning the handle 74 about the vertical pivot'124 the shaft 117 will be rocked orOs cillated in such manner as to cause one or the other of the clamping members 114 to ena e with and aress a strand or run of the cable 76' against the co-operating and relatively stationary clamping member on the arm 36. It is to be noted, moreover, that the handle 74 is moved by the. operator in the direction that. is desired to movethe presser Thus, for instance, movement Fig. of the drawings will cause the upper ofthe arm 36 and the presser member 30 toward the left. Inorder to stop themovement of the presser member along the cutting bed it' is necessaryh'only to release the pressure on the handle 7{i,-thus freeing the. cable from the grip of. the clutch or clamping members. V

When the presser member has beenmoved into position above the die, themachine is operated to effect a pressure applyingoperation of the presser member'upon the" die, means being provided for causing actuation of the clutch mechanism whereby the power pulley 18 is clutched to the main shaft 16 to cause one reciprocation of the movable cross-head 20. Machines of this erative relation with respect to the dieand V the cuttingbed, the said means comprising preferably connections from the clutch on the main'shaft to the handle 7a so that'the operative'by proper manipulationof a sin gle ,manually-controllable means, can cause the pressermember to be moved in the desired direction from and toward arposition over the die and then through the same meanscause a trippingof the machine to effect a pressure applying movement of the presser member. The connections between the handle7-fi and the clutch tripping lever 126 (Fig. 2) comprise a link 128 pivotally connected at its lower end to said lever 126 and pivotally connected at its upper end to one arm of a bell crank 1'30 (Figs-221ml '3) pivoted at 132 to the upper end of the bracket 34. The other arm. of the bell crank 130 carriesone end ofa rod 134, the other end of which is mounted in an arm 136 pivoted to and extending upwardly from the bracket 7 34 at the other end of the machine and at the opposite end of the supporting bar, 32. Pivotally mounted on the rear endofthe arm 36 is a lever 138 (Figs. 3 and 5) which extends upwardly substantially above .the'

lineof the rod 134 and normally in contact with said rod so that upon actuation of the preferably a link llOpivota.
